Linear Motor Control TRIZ Cases
- Electromagnetic Actuator Control for Thrust Pulsation Suppression
Feedback correction of armature motion and displacement suppresses actuator thrust pulsation, improving vehicle ride comfort and steering stability.
- Linear Motor Cogging Compensation Using Stored Position Force Maps
Pre-mapped cogging forces let the control unit compensate shuttle position effects without energized coils, improving low-speed motion.
- Linear Transporter Magnetic Shield Molding for Accurate Position Detection
Integral molding of a resin magnetic shield reduces flux irregularities and enables more accurate linear transporter position detection.
- Linear Motor Voltage Control for Directional Vibration Feedback
By tuning system gain, phase, and harmonic amplitude, this case shows how linear motors deliver clear directional vibration feedback.
- Linear Motor Current Continuity for Low-Shock Stator Switching
Coordinated speed-integral transfer and digital filtering keep current continuous between stators, reducing switching shock in linear motors.
- Dual Hydrofoil Linear Drive Without Bearings or Bushings
Linkage-guided dual linear drives remove bearings and bushings, cutting friction and lubrication needs in hydrofoil boat propulsion.
- Linear Motor Position Sensing Without Reference Travel
A prebuilt sensor model matches magnet sensor responses to locate linear motor movers at startup without reference travel or dense sensor spacing.
- Motorized Window Sash Actuation with Balanced Force Control
Dual motor window actuator prevents sash twisting and binding by applying balanced force through a threaded rod mechanism.
- Optical Reflector Drive Using Groove Guide and Point-Contact Balls
Groove lines and point-contact balls guide the optical reflector rotation, resolving complexity and weight issues in mobile image stabilization.
